symfony-ux-skills AGENTS.md

A set of instructions for working with Symfony UX, a collection of tools that adds interactive frontend behavior to Symfony applications. It explains which tool fits behaviors, navigation, components, maps, and icons.

In plain words
What is it for?
Use it to guide work on JavaScript interactions, partial-page navigation, reusable Twig components, live-updating components, SVG icons, and interactive maps.
Why use it?
It removes guesswork when choosing among Symfony UX tools and records important implementation rules for them.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

symfony-ux-skills AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Symfony UX Frontend Stack

This project uses the Symfony UX frontend stack. Seven agent skills are installed to help you work with it.

Which tool to use

  • Pure JS behavior, no server round-trip -- use the stimulus skill
  • Navigation, partial page updates -- use the turbo skill
  • Reusable static UI component -- use the twig-component skill
  • Reactive component that re-renders on user input -- use the live-component skill
  • SVG icons (local or Iconify) -- use the ux-icons skill
  • Interactive maps (Leaflet / Google Maps) -- use the ux-map skill
  • Not sure which one fits -- use the symfony-ux skill (orchestrator / decision tree)

Key rules

  • Always render {{ attributes }} on the root element of a LiveComponent
  • Prefer HTML syntax (<twig:Alert />) over Twig syntax ({% component 'Alert' %})
  • Use data-model="debounce(300)|field" for text inputs in LiveComponents
  • Stimulus controllers must clean up listeners and observers in disconnect()
  • Turbo Frame IDs must match between the page and the server response
  • Use Turbo Streams when updating multiple page sections; use Frames for a single section
  • <twig:Turbo:Stream:Append> syntax is available since Symfony UX 2.22+
  • Prefer <twig:ux:icon name="..." /> over {{ ux_icon('...') }} for consistency
  • Map containers must have an explicit height (style="height: 400px;")
  • Use fitBoundsToMarkers() instead of manually calculating center/zoom
  • Lock on-demand icons before deploying: php bin/console ux:icons:lock

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
